I wasn't aware of this work. This is very interesting. Two
questions:

1) When does it failover? Meaning, if I I/O to a disk, but someone
yanks the fibrechannel plug. Does your multipath wait for a SCSI
timeout to redirect the I/O?

2) If so, have you considered trapping loop up/down events to handle
such a case? Real users of multipath tech do not want to wait 90s for
failover.
